Description
Technical Field
The utility model relates to the technical field of sewage treatment, in particular to an ozone catalytic oxidation sewage treatment device.
Background
Along with the continuous increase of sewage items in an industrial park and the increasing strictness of sewage discharge standards at present, more and more sewage treatment plants need to be added with advanced oxidation technology to achieve the aim of up-to-standard discharge of effluent COD, and the ozone catalytic oxidation technology has the advantages of good COD removal effect, low operation cost, simple and convenient operation, no sludge generation and the like in the aspect of difficult degradation organic matter removal of the industrial park and industrial wastewater, can continuously feed water or intermittently operate, is not limited by engineering scale and region, is applicable to Fan Tang, and has wide application prospect.
When sewage is treated, the existing ozone catalytic oxidation process needs to inject ozone into the sewage pool, because the ozone is gas, when the ozone is discharged into the sewage, the ozone moves upwards rapidly, at the moment, the ozone cannot be fully contacted with the sewage, the mass transfer efficiency of the ozone in water is affected, and finally the integral effect of the ozone catalytic oxidation process is not ideal, particularly when industrial wastewater with high concentration of nondegradable organic matters in the inflow water is treated, a large amount of ozone is needed to remove COD in the sewage, the treatment efficiency is not good, and a large amount of ozone resources are wasted.
Disclosure of Invention
The utility model aims to solve the technical defects and provides an ozone catalytic oxidation sewage treatment device which can effectively remove COD in sewage.
The utility model discloses an ozone catalytic oxidation sewage treatment device which comprises a flat box body, wherein a first reaction box is arranged at the lower side of one end of the flat box body, the upper end of the first reaction box is communicated with the flat box body, a second reaction box is arranged at the lower side of the other end of the flat box body, the upper end of the second reaction box is communicated with the flat box body, a water inlet pipe is arranged at the lower end of the first reaction box, a water outlet pipe is arranged at the lower end of the second reaction box, aeration heads are arranged at the bottom of the first reaction box and the bottom of the second reaction box, an extraction opening is arranged in the middle of the upper side of the flat box body, an extraction header pipe is arranged on the extraction opening, the tail end of the extraction header pipe is respectively connected with the aeration heads in the first reaction box and the second reaction box through a branch pipe, an extraction pump is arranged on the extraction header pipe, an air adding pipe is arranged at the upper side of the flat box body, and a valve is arranged on the air adding pipe.
The principle of the device is that ozone is added into the flat box body through the gas adding pipe, the gas extracting pump pumps the ozone in the flat box body to the aeration head, meanwhile, the sewage enters the first reaction box body from the water inlet pipe, then flows through the flat box body, finally enters the second reaction box body and is discharged from the water discharging pipe, a large number of tiny bubbles are formed by the ozone coming out of the aeration head, COD in the sewage is removed in the sewage rising process of the ozone bubbles, the fact that the downward flow velocity of the sewage in the second reaction box body is smaller than the rising velocity of the bubbles is needed to be described, so that the ozone stays in the device as much as possible, the waste of the ozone is reduced, when the ozone in the flat box body is reduced, the ozone can be added through the gas adding pipe, meanwhile, the sewage is contacted with the ozone on the upper side in the flat box body when flowing in the flat box body, the COD in the sewage is removed in the contact process, the fact that the bottom area of the flat box body is designed to be larger, and the sewage is also slowly removed in the flat box body under the condition that the flow velocity of the sewage of the water inlet pipe is unchanged, and the COD is better in the contact time of the sewage and ozone.
Further, a first guide plate and a second guide plate are arranged in the first reaction box and the second reaction box from top to bottom at equal cross intervals, a curved flow channel is formed between the first guide plate and the second guide plate, and bubbles and the flow of sewage in the first reaction box and the second reaction box can be increased through the first guide plate and the second guide plate, so that the reaction time is increased.
The beneficial effects of the utility model are as follows: according to the utility model, the first reaction box and the second reaction box are arranged to remove COD in sewage in the ascending process of ozone bubbles, wherein the first guide plate and the second guide plate are arranged in the first reaction box and the second reaction box to increase bubbles and the flow of sewage in the first reaction box and the second reaction box, so that the reaction time is increased, meanwhile, sewage contacts with ozone on the upper side in the flat box when flowing in the flat box, the COD in the sewage is removed in the contact process, and under the condition that the sewage flow rate of the water inlet pipe is unchanged, the larger the design of the bottom area of the flat box is, the better the COD removal effect of the ozone on the sewage is.
